Remove wordpress mentions in false positive list

[Javiery3889]

With reference to anchore/syft#1911, Syft now supports wordpress plugins through the new wordpress cataloger that was merged in anchore/syft#2218. Perhaps it would be better to remove these two lines?

grype/grype/search/only_vulnerable_targets.go

Lines 20 to 25 in 9d28137

	// There are some common target software CPE components which are not currently
	// supported by syft but are signifcant sources of false positives and should be
	// considered known for the purposes of filtering here
	known := map[string]bool{
	"wordpress": true,
	"wordpress_": true,
